@rlam3 Hi, I couldn’t reproduce the issue. I’ve tried running monaca debug as monaca preview on both Cordova and transpilable projects but there is no such error. It’d be helpful if you could tell me how to reproduce this issue. I can also take a look at your project if you submit your project here.

This was happening for me while I had my iphone plugged in via USB. Doing this created a new network (ethx / 169.254.x.x) which Monaca appeared to be trying to use rather than say localhost or wifi. Unplugging the phone from USB fixed it.
